Still you don't wanna add search feature?

Of course I do. It's even stubbed out in a branch. But it's hard. In fact, to keep a search index updated in real-time is expensive and time consuming to build. One day I'd like to make it happen, but not enough people would even use it that I think it's worthwhile just yet.

Yes, those should be much cheaper to index, but even if the index updates in near-time (however near), that would be handy. If I have saved an entry in the last day or so, I usually don’t need a search to find it again, so near time needn’t even mean just, say, five minutes.

Whoosh and Haystack should work great with Django, but if you want it to be hugely scalable, ElasticSearch is of course much recommended too.

If you are struggling with search I would recommend you look at solr. It's fairly easy and not to resource intensive to get a search running with that. I'd be happy to give you any help if you needed it.
